Silencer Central’s Banish line offers two excellent options for shooters seeking .223/5.56 caliber suppression: the Banish 223 and the newer Banish Speed K. While both excel in reducing noise and improving shooting experience, they cater to slightly different needs. Let’s dive into the key differences between these suppressors to help you choose the right one for your firearm.

Size and Weight

The most striking difference lies in their physical dimensions. Thanks to its titanium construction, the Banish 223 boasts a 7-inch length and weighs 11.4 ounces, making it a well-balanced option for most AR-15 platforms.

The Banish Speed K, however, takes compactness to the extreme. This suppressor measures a mere 4 inches long and, depending on the material chosen (Iconel or titanium), weighs 14.1 or 8.2 ounces respectively. The model I tested was the heavier and more durable Iconel model.

Noise Reduction

Both suppressors offer significant noise reduction, but the Banish 223 holds a slight edge. Silencer Central reports a 34 dB reduction at the ear with the Banish 223, putting it closer to achieving “hearing-safe” levels (generally considered around 130 dB). The Banish Speed K, on the other hand, offers a reported 20.9 dB reduction depending on the specific firearm and ammunition used. Hearing protection is still recommended for extended shooting sessions at the range for both suppressors.

Durability

The Banish 223 utilizes a titanium construction, known for its balance of strength and weight reduction. This makes it a reliable choice for normal volume shooting, even with limited full-auto applications. Like all suppressors in the BANISH lineup, the BANISH 223 is easily disassembled for cleaning and maintenance. 

The Banish Speed K, particularly the Inconel version, prioritizes extreme durability. Inconel can withstand even higher temperatures than titanium, making it ideal for sustained fire or harsh environments. However, this comes at the cost of increased weight. The titanium variant of the Speed K offers a compromise between weight and durability, but may not be suitable for the most demanding users.

Gas Blowback Comparison

Gas blowback refers to the residual gas vented back towards the shooter after firing. Both suppressors excel at mitigating this discomfort, but the Banish Speed K takes the lead. Its design incorporates “controlled flow technology” with a vented fourth baffle. This allows for efficient gas redirection, resulting in a reported increase of only 5.8% in gas blowback compared to unsuppressed firing. This minimal increase ensures a smoother shooting experience and minimizes the chance of gas getting into the shooter’s face.

The Banish 223, while still effective at reducing gas blowback, doesn’t quite match the performance of the Speed K. While specific figures aren’t readily available, I noticed a higher level of gas blowback compared to the Speed K. This is likely due to the Banish 223’s longer internal volume, which allows for more gas to accumulate before being vented. However, the benefit of slightly better noise reduction for some users may outweigh this drawback.

Applications

The Banish 223’s combination of good sound reduction, balanced weight, and titanium construction makes it a versatile choice for various applications. It’s especially suitable for hunting, where sound suppression and lighter weight are typically the most important factors. Its slightly longer length shouldn’t hinder maneuverability significantly in most hunting situations on the majority of AR-15 platforms.

The Banish Speed K truly shines in situations such as home defense or security work where compactness and maneuverability are paramount. Its tiny size makes it ideal for close-quarters combat scenarios or situations where a low profile is desired. It’s also a better fit for high-volume target shooting or mag dump sessions where durability becomes most important.

Additional Considerations

Here are some other factors to consider when choosing between these suppressors:

• Cost: The Banish 223 is currently priced slightly lower than the Banish Speed K.
• Ease of Maintenance: Both suppressors are user-serviceable for cleaning and maintenance, but the Speed K is made from a more durable material.
• Muzzle Device Compatibility: Both suppressors utilize a standard industry-standard threaded mount for easy attachment to most AR-15s.

Choosing the Rights Suppressor

The ideal choice boils down to your specific needs. Here’s a quick breakdown to help you decide:

• Prioritize sound reduction and versatility: Go with the Banish 223.
• Need maximum compactness and maneuverability: Choose the Banish Speed K.
• Heat Retention: The Inconel version of the Banish Speed K offers less heat retention and will not heat up or cause mirage issues as fast.
• Durability for sustained fire or harsh environments: Opt for the Inconel version of the Banish Speed K.

Ultimately, both the Banish 223 and the Banish Speed K are both excellent suppressors from a reputable manufacturer. By understanding their strengths and weaknesses, you can make an informed decision for your needs and experience the benefits of suppressed shooting. Make your choice at Silencer Central today.
